LOCK-HINGE.

Specification of Letters Patent.

Patented Feb. 2'7, 1912.

Application filed May 11, 1911. Serial 1%. 626,438.

To all whom it may concern.-

Be it known that I, F nmonnrorr ILLIAM BECKER, a citizen of the UnitedStates, residing at New Athens, in the county of St. Clair and State ofIllinois, have invented certain new and useful Improvements inLock-Hinges, of which the following is a specification, reference beinghad to the accompanying drawings.

This invention relates to hinge locks and more particularly to a lockfor shutter hinges whereby the shutters may be held in their openpositions.

The primary object of the present invention is to. provide a lockingdevice for shutter hinges which is of extremely simple con struction,may be manufactured atsmall cost, and can be easily and quickly manipulated to lock or release the shutter.

Still another object of the invention is to provide a shutter hinge, anda locking memher which is adapted to coact with said hinge and to engagethe movable hinge leaf secured to the shutter to hold the shutteragainst movement.

With the above and other objects in view, the invention consists of thenovel features of construction, combination and arrangement of partshereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which- Figure 1 is a side elevation of aportion of a window shutter and frame therefor showing my improved hingelock, the shutter being closed; Fig. 2 is an edge elevation, the shutterbeing open and the lock shown in its operative position; Fig. 3 is asection taken on the line 33 of Fig. 2; and Fig. 4: is adetailperspective view of the hinge having my improved lock appliedthereto.

Referring in detail to the drawing 5 designates a frame which may beeither of wood or metal in which the shutter 6 is mounted.

The shutter hinge comprises two similar leaves or plates 7 which arebent or flanged as indicated at 8 and provided with the screw receivingopenings 9 whereby they may be attached to the frame and the shutterrespectively. The hinge leaves are provided with the usual knuckles 10through which the pintle 11 is adapted to be disposed to pivotallyconnect the leaves. The portions 7 of the hinge leaves upon which theknuckles are formed are closely engaged when the shutter is closed asshown in Fig.

1. Each of these portions 7 of the'hinge leaves is provided adjacent itsupper end with an opening 12 one of which is adapted to receive thescrew 13 upon which the locking plate let is pivotally mounted. Thislocking plate is of substantially semicircular form and has its free endportion bent out of the plane of the pivoted portion of the plate oroffset as shown at 15, for engagement with the inner face of the movablehinge leaf which is secured to the shutter, when the shutter is in itsopen position as shown in Fig. 2. A finger plate 16 is formed on thelocking plate by means of which said plate may be readily moved to itslocking position or lifted so that the shutter may be closed.

In the operation of my improved locking device, the shutter is moved toits open position against the wall of the building so as to dispose theportions 7 of the hinge leaves in substantially the same plane. Thelooking plate is then swung downwardly upon the upper end of the movableplate which is carried by the shutter so that the offset portion 15 ofthe locking plate engages upon the opposite side of the movable hingeleaf to that of the stationary plate on which the locking leaf ispivotally mounted. It will thus be seen that the shutter is securelyheld in its open position so that the wind will not blow the sameclosed, thus avoiding breakage of the shutter and the glass panes of thewindow sash. The device is extremely simple, and may be easily andquickly operated to securely hold the shutters against movement. Byproviding both of the leaves of the shutter hinges with one of theopenings 12, the locking plate may be readily attached to either theleft or right hand hinge, without requiring any change in the form ofsaid plate.

From the foregoing it is believed that the construction and operation ofmy improved locking device will be readily understood. The movablelocking plates may be manufactured at small cost and readily attached tothe hinges without necessitating the employment of skilled labor. Thedevice is also extremely durable and highly eflicient in practical use.

Having thus described the invention what is claimed is The combinationwith the two leaves of a hinge; of a locking device therefor, comprisinga crescent shaped plate of sheet tending from said medial portion of the10 metal twisted to bring the two ends into plate.
